This Radius of a Circle calculator computes the radius of a circle given the circle's center and a point Circleanywhere on the circle.
INSTRUCTIONS: Enter the following:
Radius: The calculator returns the radius of the circle defined by these two points.
To CLICK HERE. The is typically as follows: X2 + bX + Y2 + dY + e = 0,
Note, the radius in this calculation is simply the distance between the two points. The circle's center can be placed anywhere in the X-Y Plane. The circle in this equation is centered at the point (h,k) and the point on the circle is (x,y)
